This paper investigates Wittgenstein’s account of the relation between elementary and molecular propositions (and thus, also, the propositions of logic) in the Tractatus Logico-Philosophicus. I start by sketching a natural reading of that relation – which I call the “bipartite reading” – holding that the Tractatus gives an account of elementary propositions, based on the so-called picture theory, and a different account of molecular ones, based on the principle of truth- functionality. I then show that such a reading cannot be (...) attributed to Wittgenstein, because he holds the view that an explanation of logical complexity is already given by a correct account of the (pictorial) nature of elementary propositions; this is implied in his claim that “an elementary proposition contains all logical constants/operations in itself”. After clarifying Wittgenstein’s notion of an operation from the Notes on Logic to the Tractatus, I finally explain why Wittgenstein claims that an elementary proposition contains all logical operations in itself, and hence why he can be said to provide a unified (and thus not bipartite) account of language and logic.

This article was first published in 1982 in Educational Analysis (4, 75–91) and republished in 1998 (Hirst, P. H., & White, P. (Eds.), Philosophy of education: Major themes in the analytic tradition, Vol. 1, Philosophy and education, Part 1, pp. 61–78. London: Routledge). I was then a lecturer in philosophy of education at Sheffield University teaching the subject to Master’s students on both full- and part-time programmes. My first degree was in philosophy, read under D. W. Hamlyn and David Cooper (...) and, given their interests, inevitably emphasized the philosophy of language, in particular the work of Wittgenstein in this field. When I subsequently turned my attention to the philosophy of education it seemed obvious to me that there were serious problems with Professor Peters’ approach to language, and I had particular difficulties with his approach to criteria, meaning theory and what seemed an odd interpretation of a transcendental argument. This article thus set out to show that the then dominant form of philosophy of education seemed not to take account of developments in the philosophy of language that preceded Professor Peters’ early work by at least a decade and which cast serious doubt on the enterprise as it was then understood. As the articles in the 1998 collection indicate, I was not alone in thinking there was something amiss, although at the time I seemed to be ploughing a somewhat lonely furrow. In revisiting this early article some 30 years after it was first published I have found to my surprise that there is little I would now change, although I have been forcibly reminded of the very lively discussions Professor Peters and I had over these issues. The fact that there is little I would now add to, or subtract from, my critique is in itself a telling comment on the enduring and influential legacy of the approach to the philosophy of education that Professor Peters championed so powerfully.

Modality and Anti-Metaphysics critically examines the most prominent approaches to modality among analytic philosophers in the twentieth century, including essentialism. Defending both the project of metaphysics and the essentialist position that metaphysical modality is conceptually and ontologically primitive, Stephen McLeod argues that the logical positivists did not succeed in banishing metaphysical modality from their own theoretical apparatus and he offers an original defence of metaphysics against their advocacy of its elimination. -/- Seeking to assuage the sceptical worries which underlie modal (...) anti-realism, McLeod provides an original contribution to essentialist epistemology, engaging with current debates about modality and suggesting that standard essentialist approaches to some issues in the philosophies of logic and language require revision. -/- This book offers valuable insights to professional philosophers, postgraduates and advanced undergraduates interested in metaphysics, philosophy of logic or the history of twentieth-century analytic philosophy.
